Growing Tips & Guides

Description

Product Overview

Stoneroot (Collinsonia canadensis), also commonly known as Richweed or Horse Balm, is a herbaceous perennial native to eastern North America. Belonging to the Lamiaceae family, this distinctive woodland plant is recognized for its broad green foliage, aromatic leaves, upright stems, and delicate pale-yellow flowers.

Stoneroot Seeds offer gardeners an opportunity to cultivate a woodland herb suitable for native plant gardens within its natural range, shaded perennial borders, and botanical planting collections. The plant develops opposite, oval-shaped leaves with toothed margins and produces branching clusters of small flowers during the later part of the growing season.

Collinsonia canadensis naturally occurs in moist, fertile woodland environments, where it grows in partial shade and sheltered conditions. Its attractive foliage and subtle flowering characteristics make it an interesting addition to woodland-inspired garden landscapes.

As a herbaceous perennial, Stoneroot can return during subsequent growing seasons from its established underground root system when suitable conditions are maintained.

    How to plant your seeds

    Follow these simple steps to give your seeds the best start.

    1. Prepare your soil & tray

      Fill trays or small pots with seed-starting mix. Press gently to settle—no need to pack tight.

    2. Sow seeds at the right depth

      Plant roughly 2–3× the seed’s width deep. Tiny seeds can be pressed lightly into the surface.

    3. Water & keep warm

      Mist or bottom-water. Cover until sprouting if the packet suggests it. Keep in a bright, warm spot.
